Take a look at the reviews around and you will notice how bad the color reproduction of the Z1 (I never said anything about the Z2 - but the sensor is the same). Colors are not accurate, brightness is too high and it lacks saturation. As long as you canīt shoot in raw you are limited by the way Sony implemented the Camera. They did the same on the Z and the Z1, although the Z also lacked a decent camera.
I owned a Z1 and the cameras are the same, they take decent pictures and if you can live withe colors, the rather bad low light pictures and the slow focus, fine, live with it. Be happy and go your way.
I canīt and that is all I said!
